Like the title says I'm looking to buy resource packs (mainly because I cannot create anything myself), but what I'm wondering is, what are the most sold ones and which ones go best with RTP? The games I will make are usually just the medieval JRPG games, so I do not need any School/Horror/WRPG resource packs. I have also seen the post which states what resource packs go with each other, but what I want to know is, when I buy let's say, a time-fantasy pack, can you clearly see they are different from the defaults?
I hope this is enough information, if not, feel free to ask me anything!

Time fantasy is in a whole other tileset category when it comes to looks. I would recommend the Fsm tilesets if you're looking for something that you can use the rtp with. There are two packs out right now for it, and a 3rd one is on its way out soon so its a fairly flexible tileset.

Here's a thread that talks about which graphics pack works with the MV RTP. Anything made for VX/Ace may work with MV too, but you'll have to resize the images unless you use Shaz's conversion plugin that changes MV so it can use 32x32 px resources.
